F6 INDICATION MAY MEAN THAT THERE IS A PROBLEM WITH THE BLOWER MOTOR. WHEN THE BLOWER MOTOR GETS HEATED UP (WHEN ITS WINDING BECOMES WEAK) THIS MAY HAPPEN. SO U GET UR BLOWER MOTOR AND PCB BOARD CHECKED.

Mystery message "wait" appears above "following schedule" display line on our Th8000. Ac does not come on even when temperature is in range. Fan operates ok. Is "wait" setting one I can reset? Maybe a compressor issue rather than thermostat? Thanks

EE means energy efficiency. hen EE is displayed there can be a defective thermistor or insufficient ventilation.

The
following works on some A/C system: "When EE is displayed, press
"energy save" and "zone control" simultaneously for about 5 secs"

Try
also testing the system in auto mode, check ventilation and if possible
test thermistor by reading impedance with a multimeter.

If when EE is displayed the unit also becomes non-responsive and does not turn off, then the problem may also be a defective controller board. Other parts, included the ones mentioned before, must be tested before replacing the control module.

When EE:EE is displayed on remote control , press "Energy Save" &"Zone Control" buttons simultaneously for longer than 3 secs. The error code will then be displayed on the LCD.After getting error code, please write here to get solution. Thanks.

It means that an error has occurred. If you have a 4 button comfort control. Follow these steps to reset:To initiate a RESET, do the following in the orderlisted:1) Turn control on to ensure annunciator data and light are present. If data and light are present, continue to next step. Depress MODE switch to activate annunciator light.Simultaneously depress the bottom two buttons (temperature UP and DOWN) and hold.While holding these buttons down, depress the MODE button once and release.Release the two buttons previously held down. Depress the MODE button once again.At this time the light should extinguish, and the mode should register “OFF”. If not, repeat these steps.Retest system ensuring that all functions are presentand operational.

If you have the five button comfort control. Turn the unit off and hold down the mode and zone buttons together. While holding them down, turn the thermostat back on. Hold the buttons down until an FF appears on the screen. Release the buttons and the display should return to normal. If not, try it again.

The A/C pushbutton control module (N22) has DTC memory and data output. The diagnostic trouble codes and data are displayed via the temperature display window. The stored DTC's will remain in memory even with the vehicle battery disconnected.

The DTC memory differentiates between current and intermittent faults.

Numerous DTC's can also be read with the Hand-Held Tester (HHT).

Preparations for DTC Readout

Review 11, 12, 13, 14, 15, 21, 22, 31, 31, 41

Ignition: ON

Temperature selector: left: "HI"; right: "LO"

Ignition: OFF

Ignition: ON

Within 20 seconds press REST and EC simultaneously for more than 5 seconds.

The LED in Recirculated Air flashes and the display shows "d1A".

Press AUTO repeatedly until all DTC's are displayed. Record each DTC as it is displayed.

Each fault (short circuit, open circuit) is assigned a DTC. Thus in the left display: "E1" appears, and the right display indicates the DTC. The current faults (refer to table) are displayed first, next, the intermittant failures (e.g. 45 °5) are displayed in the display window next to the FAN symbol. By pressing the right AUTO the next DTC is displayed.

To erase: Can only be performed after all faults have been readout. Press left AUTO and right AUTO buttons simultaneously for more than 2 seconds and the display shows: left: "d" and right: "FF". To cancel erase: By pressing the left AUTO button, the current faults will appear again.

Select a base temperature setting.

Turn ignition OFF, to end test.

Note:
Due to instrument cluster (IC) series interface, DTC's may be stored in IC memory, therefore readout and erase DTC's from IC memory.
